The Hesse suicide strikes a troubling chord in the household of Decker and his wife, Rina Lazarus, now that they've taken in Gabe Whitman—the gifted and brilliant fifteen-year-old son of a killer—whose own unexplained comings and goings only remind Decker that he knows almost nothing about the secretive boy living under his roof. But it's a second teen suicide—a young girl who attended the same exclusive prep school as Gregory Hesse—that points Decker and his detectives down a dark alley of twisted allegiances and unholy alliances . . . and toward a cold-blooded group of high schoolers with a shocking predilection for guns and violence.
